| |
Hi,
This patch series are to select ARCH_HAS_FORTIFY_SOUCE on arm. A lot of architectures already select ARCH_HAS_FORTIFY_SOURCE to support CONFIG_FORTIFY_SOURCE that detects overflows at compile-time. (6974f0c4555e ("include/linux/string.h: add the option of fortified string.h functions) ARM can be built and run with CONFIG_FORTIFY_SOURCE.
Additionally, modify vdso.c to remove compile-error that happens when built arm kernel with CONFIG_FORTIFY_SOURCE.
v2 : Fix build error reported by kbuild test robot. - Add fortify_panic() in arch/arm/boot/compressed/misc.c, because arch/arm/boot/compressed/* can't find that function.
Jinbum Park (2): arm: mm: Define vdso_start, vdso_end as array arm: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE
